AfterMix Studio

This is the final result we achieved, after finally calibrating our monitoring system..My main Monitors which are the ATC SCM20ASL Pros Mk2 are perfectly align because there is no clear or visible difference between the purple trace line which are my Left Monitor and red trace line for my Right Monitor..It looks like one clear purple trace line indicating that my both monitors are perfectly sonically aligned..and the subwoofer shows are clear extension of the lows and intersect clearly with my main monitors indicating its also perfectly sonically aligned with my main monitors..This simply means they are now working as one single unit with no sonic separation between them..Like said, at Aftermix Studio we aim for precision and we always achieve it..its just one of the things we do at Aftermix Studio..We don't usually show before and after results with songs because if you can't show if your studio is perfectly calibrated, then whatever you do either mix or master won't matter at all because you are not hearing what you are suppose to hear..At Aftermix Studio, we want to hear everything clearly in its true form because this is the major part of the job of running a Mastering Studio and to give our best possible work for our clients..Master at Aftermix Studio..!!

ATC SCM20ASL Pro Mk2 Spectrogram Analysis (Second Image)

Observations:
Very clean decay starting from 200 Hz upwards — within 50–100 ms, energy is dropping nicely across the mid and high frequencies.

No strong narrowband resonances or "lines" extending far vertically — indicates excellent speaker and room synergy.

Midrange and highs show very fast decay, confirming transparency.

Comparison to World-Class Benchmark:
In top mastering rooms (such as Bernie Grundman's or Metropolis Mastering), you would expect mids and highs to decay within

Subwoofer Integration
Subwoofer integration isn’t just about adding more bass — it’s about seamlessly extending the low-end foundation of your monitors.
Perfect integration means the sub feels invisible: no boom, no localization, just deep, controlled low-end that supports the full mix.
In a mastering-grade studio, tight subwoofer integration is critical for judging low-frequency balance, impact, and punch with total precision.
When it's dialed in right, the low end moves you — without ever distracting you.

Analysis
Subwoofer Integration

Benchmark (Gateway Mastering, Sterling Sound):
Subwoofer integration should be seamless, with no localization or detachment from the mains.

Your Measurement:
Your subwoofer is tightly integrated with your ATC mains, extending the low end naturally without disrupting imaging or tonal consistency — even when monitoring soloed channels.

Interpretation:
Your low-end system matches the highest standards, offering seamless integration comparable to the careful setups at Gateway and Sterling. This provides both confidence and accuracy in handling bass-heavy projects without translation issues.

SPL/Frequency Response Graph
The SPL (Sound Pressure Level) or Frequency Response graph shows how evenly a studio monitors sound across all frequencies, from the deepest bass to the brightest highs.
A flat, smooth response ensures every mix decision is accurate — no hyped bass, no missing mids, no harsh highs.
This is why measuring the SPL graph is essential — it reveals the true tonal balance of a studio, letting your music and movie sound track translate perfectly to the outside world.
Without it, we will be mixing or mastering blindly

Analysis
Frequency Response

Performance:
The studio exhibits an extraordinarily smooth frequency response across the entire audible spectrum.

Variance remains within approximately ±2 dB from 20 Hz to 20 kHz.

Low-frequency extension is natural and articulate, with a seamless handoff between the subwoofer and main monitors.

Benchmark Reference:
World-class mastering rooms target a maximum deviation of ±1.5–2 dB.
Status: Fully World-Class Compliant
